Cannibalism, Abortion, and R/K Selection.

Reindeer herder, from "Quarter of a Million Reindeers to be Butched... after Anthrax Outbreak" : "Serbian officials have demanded a huge cull of a 250,000 reindeers by Christmas over the risk of an anthrax outbreak. Currently 730,000 animals are being kept in the Yamal Peninsula and the rest of the Yamalo-Nenets region."
Reindeer herder, from Quarter of a Million Reindeers to be Butched… after Anthrax Outbreak: “Currently 730,000 animals are being kept in the Yamal Peninsula and the rest of the Yamalo-Nenets region.”

In Hunters, Pastoralists, and Ranchers: Reindeer Economies and their Transformations [PDF,] Ingold describes the social distribution of food among hunter-gatherers. In normal times, when food is neither super-abundant nor scarce, each family basically consumes what it brings in, without feeling any particular compulsion to share with their neighbors. In times of super-abundance, food is distributed throughout the tribe, often quite freely:

Since harvested animals, unlike a plant crop, will not reproduce, the multiplicative accumulation of material wealth is not possible within the framework of hunting relations of production. Indeed, what is most characteristic of hunting societies everywhere is the emphasis not on accumulation but on its obverse: the sharing of the kill, to varying degrees, amongst all those associated with the hunter. …

The fortunate hunter, when he returns to camp with his kill, is expected to play host to the rest of the community, in bouts of extravagant consumption.

The other two ethnographies I have read of hunter-gatherers (The Harmless People, about the Bushmen of the Kalahari, and Kabloona, about the Eskimo aka Inuit) both support this: large kills are communal feasts. Hunter gatherers often have quite strict rules about how exactly a kill is to be divided, but the most important thing is that everyone gets some.

And this is eminently sensible–you try eating an entire giraffe by yourself, in the desert, before it rots.

Even in the arctic, where men can (in part of the year) freeze food for the future, your neighbor’s belly is as good as a freezer, because the neighbor you feed today will feed you tomorrow. Hunting is an activity that can be wildly successful one day and fail completely the next, so if hunters did not share with each other, soon each one would starve.

Whilst the successful hunter is required to distribute his spoils freely amongst his camp fellows, he does so with the assurance that in any future eventuality, when through bad luck he fails to find game, or through illness or old age he can no longer provide for himself and his family, he will receive in his turn. Were each hunter to produce only for his own domestic needs, everyone would eventually perish from hunger (Jochelson 1926:124). Thus, through its contribution to the survival and reproduction of potential producers, sharing ensures the perpetuation of society as a whole. …

Yet he is also concerned to set aside stocks of food to see his household through at least a part of the coming winter. The meat that remains after the obligatory festive redistribution is therefore placed in the household’s cache, on which the housewife can draw specifically for the provision of her own domestic group (Spencer 1959:149). After the herds have passed by, domestic autonomy is re-establisheddraws on its own reserves of stored food.

But what happens at the opposite extreme, not under conditions of abundance, but when everyone‘s stocks run out? Ingold claims that in times of famine, the obligation to share what little food one has with one’s neighbors is also invoked:

We find, therefore, that the incidence of generalized reciprocity tends to peak towards the two extremes of scarcity and abundance… The communal feast that follows a successful hunting drive involves the same heightening of band solidarity, and calls into play the same functions of leadership in the apportionment of food, as does the consumption of famine rations.

I am reminded here of a scene in The Harmless People in which there was not enough food to go around, but the rules of distribution were still followed, each person just cutting their piece smaller. Thomas described one of the small children, hungry, trying to grab the food bowl–not the food itself–to stop their mother from giving away their food to the next person in the chain of obligation.

Here Ingold pauses to discuss a claim by Sahlins that such social order will (or should) break down under conditions of extreme hunger:

Probably every primitive organization has its breaking-point, or at least its turning-point. Every one might see the time when co-operation is overwhelmed by the scale of disaster and chicanery becomes the order of the day. The range of assistance contracts progressively to the family level; perhaps even these bonds dissolve and, washed away, reveal an inhuman, yet most human, self-interest. Moreover, by the same measure that the circle of charity is
compressed that of ‘negative reciprocity* is potentially expanded. People who helped each other in normal times and through the first stages of disaster display now an indifference to each others’ plight, if they do not exacerbate a mutual downfall by guile, haggle and theft.

Ingold responds:

I can find no evidence, either in my reading of circumpolar ethnography, or in the material cited by Sahlins, for the existence of such a ‘turning-point’ in hunting societies. On the contrary, as the crisis deepens, generalized reciprocity proceeds to the point of dissolution of domestic group boundaries. ‘Negative reciprocity’, rather than closing in from beyond the frontiers of the household, will be expelled altogether from the wider social field, only to make its appearance within the heart of the domestic group itself.

Thus the women of the household, who are allowed to eat only after the appetites of their menfolk have been satisfied, may be left in times of want with the merest scraps of food. Among the Chipewyan, ‘when real distress approaches, many of them are permitted to starve, when the males are amply provided for’…

In situations of economic collapse, negative reciprocity afflicts not only the domestic relations between husband and wife, but those between mother and child, and between parent and grandparent. If the suckling of children is the purest expression of generalized reciprocity, in the form of a sustained one-way flow, then infanticide must surely represent the negative extreme. Likewise, old or sick members of the household will be the first to be abandoned when provisions run short. Even in normal times, individuals who are past labour have to scavenge the left-overs of food and skins (Hearne 1911:326). In the most dire circumstances of all, men will consume their starving wives and children before turning upon one another.

Drawing on Eskimo material, Hoebel derives the following precepts of cannibal conduct: Not unusually . . . parents kill their own children to be eaten. This act is no different from infanticide. A man may kill and eat his wife; it is his privilege. Killing and eating a relative will produce no legal consequences. It is to be presumed, however, that killing a non-relative for food is murder. (1941:672, cited in Eidlitz 1969:132)

In short, the ‘circle of charity’ is not compressed but inverted: as the threat of starvation becomes a reality, the legitimacy of killing increases towards the centre. The act is ‘inhuman’ since it strips the humanity of the victim to its organic, corporeal substance. If altruism is an index of sociability, then its absolute negation annuls the sodality of the recipient: persons, be they human or animal, become things.

297px-world_population_v3-svgThis is gruesome, but let us assume it is true (I have not read the accounts Ingold cites, so I must trust him, and I do not always trust him but for now we will.)

The cold, hard logic of infanticide is that a mother can produce more children if she loses one, but a child who has lost its mother will likely die as well, along with all of its siblings. One of my great-great grandmothers suffered the loss of half her children in infancy and still managed to raise 5+ to adulthood. Look around: even with abortion and birth control widely available, humanity is not suffering a lack of children, but an over-abundance.

 

c08pnclw8aapot6Furthermore, children starve faster and are easier to kill than parents; women are easier to kill than men; people who live with you are easier to kill than people who don’t.

No one said GNON has a heart.

Before we condemn these people, let us remember that famine is a truly awful, torturous way to die, and that people who are on the brink of starving to death are not right in their minds. As “They’re not human”: How 19th-century Inuit coped with a real-life invasion of the Walking Dead recounts:

“Finally, as the footsteps stopped just outside the igloo, it was the old man who went out to investigate.

“He emerged to see a disoriented figure seemingly unaware of his presence. The being was touching the outside of the igloo with curiosity, and raised no protest when the old man reached his hand out to touch its cheek.

“His skin was cold. …

The figures, of course, were the last survivors of the Franklin Expedition. They had buried their captain. They had seen their ship entombed by ice. They had eaten the dead to survive. …

Inuit nomads had come across streams of men that “didn’t seem to be right.” Maddened by scurvy, botulism or desperation, they were raving in a language the Inuit couldn’t understand. In one case, hunters came across two Franklin Expedition survivors who had been sleeping for days in the hollowed-out corpses of seals. …

The figures were too weak to be dangerous, so Inuit women tried to comfort the strangers by inviting them into their igloo. …

The men spit out pieces of cooked seal offered to them. They rejected offers of soup. They grabbed jealous hold of their belongings when the Inuit offered to trade.

When the Inuit men returned to the camp from their hunt, they constructed an igloo for the strangers, built them a fire and even outfitted the shelter with three whole seals. …

When a small party went back to the camp to retrieve [some items], they found an igloo filled with corpses.

The seals were untouched. Instead, the men had eaten each other. …

In 1854, Rae had just come back from a return trip to the Arctic, where he had been horrified to discover that many of his original Inuit sources had fallen to the same fates they had witnessed in the Franklin Expedition.

An outbreak of influenza had swept the area, likely sparked by the wave of Franklin searchers combing the Arctic. As social mores broke down, food ran short.

Inuit men that Rae had known personally had chosen suicide over watching the slow death of their children. Families had starved for days before eating their dog teams. Some women, who had seen their families die around them, had needed to turn to the “last resource” to survive the winter.

Infanticide, cannibalism, and human sacrifice were far more common prior to 1980 or so than we like to think; God forbid we should ever know such fates.

According to Wikipedia:

“Many Neolithic groups routinely resorted to infanticide … Joseph Birdsell believed that infanticide rates in prehistoric times were between 15% and 50% of the total number of births,[10] while Laila Williamson estimated a lower rate ranging from 15% to 20%.[6]:66 Comparative anthropologists have calculated that 50% of female newborn babies were killed by their parents during the Paleolithic era.[12] Decapitated skeletons of hominid children have been found with evidence of cannibalism.[13]

400px-Magliabchanopage_73r“Three thousand bones of young children, with evidence of sacrificial rituals, have been found in Sardinia. Pelasgians offered a sacrifice of every tenth child during difficult times. Syrians sacrificed children to Jupiter and Juno. Many remains of children have been found in Gezer excavations with signs of sacrifice. Child skeletons with the marks of sacrifice have been found also in Egypt dating 950-720 BCE. In Carthage “[child] sacrifice in the ancient world reached its infamous zenith.”[11]:324  …

“According to Shelby Brown, Carthaginians, descendants of the Phoenicians, sacrificed infants to their gods.[25] Charred bones of hundreds of infants have been found in Carthaginian archaeological sites. One such area harbored as many as 20,000 burial urns.[25]

Picture 4Plutarch (c. 46–120 AD) mentions the practice, as do Tertullian, Orosius, Diodorus Siculus and Philo. The Hebrew Bible also mentions what appears to be child sacrifice practiced at a place called the Tophet (from the Hebrew taph or toph, to burn) by the Canaanites. Writing in the 3rd century BCE, Kleitarchos, one of the historians of Alexander the Great, described that the infants rolled into the flaming pit. Diodorus Siculus wrote that babies were roasted to death inside the burning pit of the god Baal Hamon, a bronze statue.

“… the exposure of newborns was widely practiced in ancient Greece, it was even advocated by Aristotle in the case of congenital deformity — “As to the exposure of children, let there be a law that no deformed child shall live.”[30]

“The practice was prevalent in ancient Rome, as well. … A letter from a Roman citizen to his sister, or a pregnant wife from her husband,[35] dating from 1 BC, demonstrates the casual nature with which infanticide was often viewed:

“I am still in Alexandria. … I beg and plead with you to take care of our little child, and as soon as we receive wages, I will send them to you. In the meantime, if (good fortune to you!) you give birth, if it is a boy, let it live; if it is a girl, expose it.” [36][37]

CgxAZrOUYAEeANF“In some periods of Roman history it was traditional for a newborn to be brought to the pater familias, the family patriarch, who would then decide whether the child was to be kept and raised, or left to die by exposure.[39] The Twelve Tables of Roman law obliged him to put to death a child that was visibly deformed. …

“According to William L. Langer, exposure in the Middle Ages “was practiced on gigantic scale with absolute impunity, noticed by writers with most frigid indifference”.[47]:355–356 At the end of the 12th century, notes Richard Trexler, Roman women threw their newborns into the Tiber river in daylight.[48]” …

400px-Kodeks_tudela_21“Philosopher Han Fei Tzu, a member of the ruling aristocracy of the 3rd century BC, who developed a school of law, wrote: “As to children, a father and mother when they produce a boy congratulate one another, but when they produce a girl they put it to death.”[63]

“Buddhist belief in transmigration allowed poor residents of the country to kill their newborn children if they felt unable to care for them, hoping that they would be reborn in better circumstances. Furthermore, some Chinese did not consider newborn children fully “human”, and saw “life” beginning at some point after the sixth month after birth.[65]

“Contemporary writers from the Song dynasty note that, in Hubei and Fujian provinces, residents would only keep three sons and two daughters (among poor farmers, two sons and one daughter), and kill all babies beyond that number at birth.[66]”

“It was not uncommon that parents threw a child to the sharks in the Ganges River as a sacrificial offering. The British colonists were unable to outlaw the custom until the beginnings of the 19th century.[82]:78

“According to social activists, female infanticide has remained a problem in India into the 21st century, with both NGOs and the government conducting awareness campaigns to combat it.[83] …

“In the Eastern Shoshone there was a scarcity of Indian women as a result of female infanticide.[100] For the Maidu Native Americans twins were so dangerous that they not only killed them, but the mother as well.[101] In the region known today as southern Texas, the Mariame Indians practiced infanticide of females on a large scale. Wives had to be obtained from neighboring groups.[102]

Meanwhile in the Americas:

In 2005 a mass grave of one- to two-year-old sacrificed children was found in the Maya region of Comalcalco. The sacrifices were apparently performed for consecration purposes when building temples at the Comalcalco acropolis.[2] …

Archaeologists have found the remains of 42 children sacrificed to Tlaloc (and a few to Ehecátl Quetzalcóatl) in the offerings of the Great Pyramid of Tenochtitlan. In every case, the 42 children, mostly males aged around six, were suffering from serious cavities, abscesses or bone infections that would have been painful enough to make them cry continually. Tlaloc required the tears of the young so their tears would wet the earth. As a result, if children did not cry, the priests would sometimes tear off the children’s nails before the ritual sacrifice.[7]

And don’t get me started on cannibalism.

It is perhaps more profitable to ask which cultures didn’t practice some form of infanticide/infant sacrifice/cannibalism than which ones did. The major cases Wikipedia notes are Ancient Egypt, Judaism, Christianity, and Islam (we may note that Judaism in many ways derived from ancient Egypt, and Christianity and Islam from Judaism.) Ancient Egypt stands out as unique among major the pre-modern, pre-monotheistic societies to show no signs of regular infanticide–and even in the most infamous case where the Egyptian pharaoh went so far as to order the shocking act, we find direct disobedience in his own household:

3 And when she [Jochebed] could not longer hide him [the baby], she took for him an ark of bulrushes, and daubed it with slime and with pitch, and put the child therein; and she laid it in the flags by the river’s brink.4 And his sister stood afar off, to wit what would be done to him.

pharaohs_daughter-15 And the daughter of Pharaoh came down to wash herself at the river; and her maidens walked along by the river’s side; and when she saw the ark among the flags, she sent her maid to fetch it.

6 And when she had opened it, she saw the child: and, behold, the babe wept. And she had compassion on him, and said, “This is one of the Hebrews’ children.”

7 Then said his sister to Pharaoh’s daughter, “Shall I go and call to thee a nurse of the Hebrew women, that she may nurse the child for thee?”

8 And Pharaoh’s daughter said to her, “Go.” And the maid went and called the child’s mother.

9 And Pharaoh’s daughter said unto her, “Take this child away, and nurse it for me, and I will give thee thy wages.” And the women took the child, and nursed it.

10 And the child grew, and she brought him unto Pharaoh’s daughter, and he became her son. And she called his name Moses: and she said, “Because I drew him out of the water.”

–Exodus 2:3-10

I don’t know the actual infanticide numbers in modern Muslim countries (le wik notes that poverty in places like Pakistan still drives infanticide) but it is officially forbidden by Islam.

According to Abortions in America: • Black women are five times more likely to abort than white women. • 69% of pregnancies among Blacks are unintended, while that number is 54% among Hispanics and 40% of pregnancies among Whites. • Planned Parenthood, ... has located 80% of its abortion clinics in minority neighborhoods

• 69% of pregnancies among Blacks are unintended, while that number is 54% among Hispanics and 40% of pregnancies among Whites.
• Planned Parenthood, … has located 80% of its abortion clinics in minority neighborhoods

Today, between the spread of Abrahamic religions, Western Values, and general prosperity, the infanticide rate has been cut and human sacrifice and cannibalism have been all but eliminated. Abortion, though, is legal–if highly controversial–throughout the West and Israel.

According to the CDC, the abortion rate for 2013 was 200 abortions per 1,000 live births, or about 15% of pregnancies. (The CDC also notes that the abortion rate has been falling since at least 2004.) Of these, “91.6% of abortions were performed at ≤13 weeks’ gestation; … In 2013, 22.2% of all abortions were early medical abortions.”

To what can we attribute this anti-infanticide sentiment of modern monotheistic societies? Is it just a cultural accident, a result of inheritance from ancient Egypt, or perhaps the lucky effects of some random early theologian? Or as the religious would suggest, due to God’s divine decree? Or is it an effect of the efforts parents must expend on their few children in societies where children must attend years of school in order to succeed?

According to Wikipedia:

In ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. The focus upon either increased quantity of offspring at the expense of individual parental investment of r-strategists, or reduced quantity of offspring with a corresponding increased parental investment of K-strategists, varies widely, seemingly to promote success in particular environments. …

In r/K selection theory, selective pressures are hypothesised to drive evolution in one of two generalized directions: r– or K-selection.[1] These terms, r and K, are drawn from standard ecological algebra as illustrated in the simplified Verhulst model of population dynamics:[7]

d N d t = r N ( 1 − N K ) {\frac {dN}{dt}}=rN\left(1-{\frac {N}{K}}\right)

where r is the maximum growth rate of the population (N), K is the carrying capacity of its local environmental setting, and the notation dN/dt stands for the derivative of N with respect to t (time). Thus, the equation relates the rate of change of the population N to the current population size and expresses the effect of the two parameters. …

As the name implies, r-selected species are those that place an emphasis on a high growth rate, and, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K).[8] A typical r species is the dandelion Taraxacum genus.

In unstable or unpredictable environments, r-selection predominates due to the ability to reproduce quickly. There is little advantage in adaptations that permit successful competition with other organisms, because the environment is likely to change again. Among the traits that are thought to characterize r-selection are high fecundity, small body size, early maturity onset, short generation time, and the ability to disperse offspring widely. …

By contrast, K-selected species display traits associated with living at densities close to carrying capacity, and typically are strong competitors in such crowded niches that invest more heavily in fewer offspring, each of which has a relatively high probability of surviving to adulthood (i.e., low r, high K). In scientific literature, r-selected species are occasionally referred to as “opportunistic” whereas K-selected species are described as “equilibrium”.[8]

In stable or predictable environments, K-selection predominates as the ability to compete successfully for limited resources is crucial and populations of K-selected organisms typically are very constant in number and close to the maximum that the environment can bear (unlike r-selected populations, where population sizes can change much more rapidly).

Traits that are thought to be characteristic of K-selection include large body size, long life expectancy, and the production of fewer offspring, which often require extensive parental care until they mature.

Of course you are probably already aware of Rushton’s R/K theory of human cultures:

Rushton’s book Race, Evolution, and Behavior (1995) uses r/K selection theory to explain how East Asians consistently average high, blacks low, and whites in the middle on an evolutionary scale of characteristics indicative of nurturing behavior. He first published this theory in 1984. Rushton argues that East Asians and their descendants average a larger brain size, greater intelligence, more sexual restraint, slower rates of maturation, and greater law abidingness and social organization than do Europeans and their descendants, who average higher scores on these dimensions than Africans and their descendants. He theorizes that r/K selection theory explains these differences.

I’d be remiss if I didn’t also mention that the article states, “Rushton’s application of r/K selection theory to explain differences among racial groups has been widely criticised. One of his many critics is the evolutionary biologist Joseph L. Graves, who has done extensive testing of the r/K selection theory with species of Drosophila flies. …”

Genetics or culture, in dense human societies, people must devote a great deal of energy to a small number of children they can successfully raise, leading to the notion that parents are morally required to put this effort into their children. But this system is at odds with the fact that without some form of intervention, the average married couple will produce far more than two offspring.

Ultimately, I don’t have answers, only theories.

Do Chilblains Affect Blacks More than Whites?

toes afflicted with chilblains
toes afflicted with chilblains

While tromping through a blizzard, seeking insight into circum-polar peoples, I discovered a condition called chilblains. The relevant Wikipedia page is rather short:

Chilblains … is a medical condition that occurs when a predisposed individual is exposed to cold and humidity, causing tissue damage. It is often confused with frostbite and trench foot. Damage to capillary beds in the skin causes redness, itching, inflammation, and sometimes blisters. Chilblains can be reduced by keeping the feet and hands warm in cold weather, and avoiding extreme temperature changes. Chilblains can be idiopathic (spontaneous and unrelated to another disease), but may also be a manifestation of another serious medical condition that needs to be investigated.

The part they don’t mention is that it can really hurt.

The first HBD-related question I became interested in–after visiting a black friend’s house and observing that she was comfortable without the AC on, even though it was summer–is whether people from different latitudes prefer different temperatures. It seems pretty obvious: surely people from Yakutsk prefer different temperatures than people from Pakistan. It also seems easy to test: just put people in a room and give them complete control over the thermostat. And yet, I’d never heard anyone discuss the idea.

Anyway, the perfunctory Wikipedia page on chilblains mentioned nothing about racial or ethnic predisposition to the condition–even though surely the Eskimo (Inuit) who have genetic admixture from both ice-age Neanderthals and Denisovans:

“Using this method, they found two regions with a strong signal of selection: (i) one region contains the cluster of FADS genes, involved in the metabolism of unsaturated fatty acids; (ii) the other region contains WARS2 and TBX15, located on chromosome 1.” …

“TBX15 plays a role in the differentiation of brown and brite adipocytes. Brown and brite adipocytes produce heat via lipid oxidation when stimulated by cold temperatures, making TBX15 a strong candidate gene for adaptation to life in the Arctic.” …

“The Inuit DNA sequence in this region matches very well with the Denisovan genome, and it is highly differentiated from other present-day human sequences, though we can’t discard the possibility that the variant was introduced from another archaic group whose genomes we haven’t sampled yet,” Dr. Racimo said.

The scientists found that the variant is present at low-to-intermediate frequencies throughout Eurasia, and at especially high frequencies in the Inuits and Native American populations, but almost absent in Africa.

Sub-Saharan Africans have their own archaic admixture, but they have very little to no ice-age hominin–which is probably good for them, except for those who’ve moved further north.

Imagine my surprised upon searching and discovering very little research on whether chilblains disproportionately affects people of different races or ethnicities. If you were a dermatologist–or a genetically prone person–wouldn’t you want to know?

So here’s what I did find:

The National Athletic Trainers Association Position Statement on Cold Injuries notes:

Black individuals have been shown to be 2 to 4 times more likely than individuals from other racial groups to sustain cold injuries. These differences may be due to cold weather experience, but are likely due to anthropometric and body composition differences, including less-pronounced CIVD, increased sympathetic response to cold exposure, and thinner, longer digits.3,6

I think CIVD=Cold-Induced Vasodilation

The Military Surgeon: Journal of the Association of Military Surgeons of the United States, Volumes 36-37, states:

c2ijvyvveaaehdz c2ijw49vqaajuou

The text continues with descriptions of amputating rotting feet.

A PDF from the UK, titled “Cold Injury,” notes:

c2ilp17uaaaonao

Notice that the incidence of chilblains is actually less in extremely cold places than moderately cold places–attributed here to people in these places being well-equipped for the cold.

c2ilp4evqaet4lu

Finally I found a PDF of a study performed, I believe, by the US Military, Epidemiology of US Army Cold Weather Injuries, 1980-1999:

picture-2

While I would really prefer to have more ethnic groups included in the study, two will have to suffice. It looks like trench foot may be an equal-opportunity offender, but chilblains, frostbite, and other cold-related injuries attack black men (at least in the army) at about 4x the rate of white men, and black women 2x as often as white women (but women in the army may not endure the same conditions as men in the army.)

On a related note, while researching this post, I came across this historic reference to infectious scurvy and diabetes, in the Journal of Tropical Medicine and Hygiene, Volumes 4-5 (published in 1902):

Note: this is why it is important to discard bad theories after they’ve been disproven. Otherwise, you kill your scurvy victims by quarantining them instead of giving them oranges.

Addendum to Race: The Social Construction of a Biological Reality

Now I am going to try to express a bit of nuance, staking out a position somewhere between “race isn’t real” and “Derbyshire is a race traitor.”

In the “race isn’t real” department, we have Sarah Zhang’ Will the Alt-Right Promote a New Kind of Racist Genetics?:

In the genomic age, it is now easy to compare the DNA of people from around the world. And it has indeed revealed that our racial categories are fuzzy proxies for genetic difference—an African man may be more closely related to an Asian than to another African.

From there, Zhang basically tries to argue that race doesn’t real even though genetics and medical science sure make it look real, that the differences in the distribution of genetic traits in large, historically isolated populations don’t matter because of a few tiny populations that are the genetic equivalent of the Basque language.

Kyle Field
Kyle Field, population 102,700

Remember, the world’s entire population of Bushmen wouldn’t even fill the Texas A&M football stadium. Combine them with a few other tiny populations, like the Khoikhoi and Pygmies, and you’re still looking at <1 million people.  Meanwhile, there are billions of Europeans, west Africans, and east Asians.

Mundane racial categories work just fine for the vast majority of people, including the vast majority of Americans, who are not drawn from a rainbow of racially-mixed groups like Tuaregs or fringe outliers like the Bushmen, but from distinct populations of West Africans, Europeans (primarily NW Euros,) Native Americans, and East Asians. If I say someone is “black” or “white,” not only do you understand what I mean, there is an actually consistent genetic reality underlying my statements–in almost 100% of cases, a genetic test would in fact confirm that the people I call “black” are actually primarily Sub-Saharan African by ancestry and the people I call “white” are primarily European by ancestry. Exceptions like Rachel Dolezal are quite rare.

Zhang is trying to argue that you can’t make a reasonable argument about the average distribution of traits between whites, blacks, and Asians in the US because there is a handful of tiny, genetically isolated populations over in Africa. A does not follow from B.

On the other side of the coin, we have people who believe it’s morally imperative to only marry people from one’s own race.

Most of the time, people fall in love with people from their own culture and ethnic group. This is what we’d expect, because you’re more likely to meet and share values with people from your own group. (Interestingly, most people are more genetically similar to their spouses than they are to the average person in their community, not because they married a close relative, but because similar genes make for similar people.)

But some people, for whatever reasons, marrying within their own group isn’t a real option. (White men who are under 5’5″, for example.) These people are looking out for their own best interests–really, if you’re considering calling Derbyshire a race traitor, you’re probably thinking too much about other people’s business.

Capitalism works because it self-corrects; it allows consumers to pick the best products at the best prices, and companies to hire the most talented workers for the best wages. Unlike socialism, where companies are told what and how much to produce, consumers are told what to buy and how much it will cost, and ultimately people starve in the streets, capitalism actually works. Self-interest is a powerful organizing principle that has radically increased the welfare of billions of people over the past century.

And capitalism doesn’t care about race.

Cj4IdTTXAAAhBax

Where people live in close proximity to people of other races, some of them will fall in love.

That said, don’t date people for status points or because you’re trying to prove how not-racist you are. Like Obama’s parents, most inter-racial couples don’t stay together; the majority of mixed-race children have parents who are not married–according to one study, 92% of biracial children with black fathers are born out of wedlock and 82% end up on government assistance because their fathers do not bother to take care of them.

picture-6And if you are ever tempted to compare your vagina to the UN because of the sheer number of different ethnicities that have been in it, you need to stop and re-evaluate your life for multiple reasons.

 

Ultimately, real-life decisions should be based on real-life concerns.

Right, so as we turn our car around and head back up the road, we notice an intriguing turnoff in the Congolese rainforest: a tribe of the shortest people in the world, the Pygmies. According to Wikipedia:

A pygmy is a member of an ethnic group whose average height is unusually short; anthropologists define pygmy as a member of any group where adult men are on average less than 150 cm (4 feet 11 inches) tall.[1] A member of a slightly taller group is termed “pygmoid“.[2]

The term is most associated with peoples of Central Africa, such as the Aka, Efé and Mbuti.[3] If the term pygmy is defined as a group’s men having an average height below 1.55 meters (5 feet 1 inch), then there are also pygmies in Australia, Thailand, Malaysia, the Andaman Islands,[4] Indonesia, the Philippines, Papua New Guinea, Bolivia, and Brazil,[5] including some Negritos of Southeast Asia.

Basically, whenever humans live in tropical rainforests, there’s a good chance they’ll get shorter. (Rainforests also produce pygmy elephants.) Maybe it’s because short people can move more easily through the dense forest, or an adaptation to low levels of iodine, sunlight, or other nutrients–I don’t really know.

Wikipedia estimates that there are between 250,000 and 600,000 pygmies living in the Congo rainforest:

Genetically, the pygmies are extremely divergent from all other human populations, suggesting they have an ancient indigenous lineage. Their uniparental markers represent the most ancient divergent ones right after those typically found in Khoisan peoples. African pygmy populations possess high levels of genetic diversity,[10] recent advances in genetics shed some light on the origins of the various pygmy groups. …

“We studied the branching history of Pygmy hunter–gatherers and agricultural populations from Africa and estimated separation times and gene flow between these populations. The model identified included the early divergence of the ancestors of Pygmy hunter–gatherers and farming populations ~60,000 years ago, followed by a split of the Pygmies’ ancestors into the Western and Eastern Pygmy groups ~20,000 years ago.”

But I recall–was it WestHunt?–objecting that the authors of this paper used a too-fast estimation of genetic mutation rates. Oh here it is:

There are a couple of recent papers on introgression from some quite divergent archaic population into Pygmies ( this also looks to be the case with Bushmen). Among other things, one of those papers discussed the time of the split between African farmers (Bantu) and Pygmies, as determined from whole-genome analysis and the mutation rate. They preferred to use the once-fashionable rate of 2.5 x 10-8 per-site per-generation (based on nothing), instead of the new pedigree-based estimate of about 1.2 x 10-8 (based on sequencing parents and child: new stuff in the kid is mutation). The old fast rate indicates that the split between Neanderthals and modern humans is much more recent than the age of early Neanderthal-looking skeletons, while the new slow rate fits the fossil record – so what’s to like about the fast rate? Thing is, using the slow rate, the split time between Pygmies and Bantu is ~300k years ago – long before any archaeological sign of behavioral modernity (however you define it) and well before the first known fossils of AMH (although that shouldn’t bother anyone, considering the raggedness of the fossil record).

See my review of Isaac Bacirongo and Nest's Still a Pygmy
See my review of Isaac Bacirongo and Michael Nest’s Still a Pygmy

Let’s split the difference and say that one way or another, Pygmies split off from their hunter-gatherer neighbors and became isolated in the rainforest quite a while ago.

Before we drive on, I’d like to pause and note that I’m not entirely comfortable with using the way Pygmies are sometimes used in racial discussions. Yes, they are short, but they otherwise look a lot like everyone else in the area. Pygmies go to school, often speak multiple languages, live in cities, work at real jobs, read books, operate businesses, drive cars, fall in love, get married, build houses, etc. For more on Pygmies see my review of Isaac Bacirongo’s memoir Still a Pygmy (Isaac is a Pygmy man who speaks, IIRC, 5 languagues, attended highschool, and owned/ran successful pharmacies in two different cities in the DRC before the army burned them down during a civil war.)

Now I admit that Isaac is just one guy and I don’t know what the rest of the Pygmies are like.

People over-thought ancestry long before 23 and Me
Different classes of Mexican mestizos: people over-thought ancestry long before 23 and Me

But let’s hop back in our car, for at the other end of this road we have not a small town of isolated forest-dwellers, but a large group we have so far neglected: the Native Americans.

The indigenous peoples of North and South America today number about 60 million people, plus some quantity of mixed-race people (mestizos.) In some areas these mestizos are majority European by ancestry; in others they are majority Indian; studies in Mexico, for example, estimate that 80-93% of the population is Mestizo, with Indian ancestry averaging between 31% and 66% in different regions. The people of El Salvador are about 86% mestizo; Chileans are about 40% Indian and 60% Europeans; Columbia is about 49% mestizo; etc.

Unfortunately, Wikipedia doesn’t list the total number of mestizos, and I don’t have time to calculate it, but I will note that the total population of both continents, including Canada and the USA, is about 1 billion people.

We’re not sure exactly when (or how) the Indians got here, but it looks like they arrived around 10-20,000 years ago across the then-Bering Landbridge. (I think we should also keep in mind the possibility that they could have built boats.) According to Wikipedia:

Scientific evidence links indigenous Americans to Asian peoples, specifically Siberian populations, such as the Ket, Selkup, Chukchi and Koryak peoples. Indigenous peoples of the Americas have been linked to North Asian populations by the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA.[192] There is general agreement among anthropologists that the source populations for the migration into the Americas originated from an area somewhere east of the Yenisei River. The common occurrence of the mtDNA Haplogroups A, B, C, and D among eastern Asian and Native American populations has long been recognized.[193] As a whole, the greatest frequency of the four Native American associated haplogroups occurs in the AltaiBaikal region of southern Siberia.[194] Some subclades of C and D closer to the Native American subclades occur among Mongolian, Amur, Japanese, Korean, and Ainu populations.[193][195]

Genetic studies of mitochondrial DNA (mtDNA) of Amerindians and some Siberian and Central Asian peoples also revealed that the gene pool of the Turkic-speaking peoples of Siberia such as Altaians, Khakas, Shors and Soyots, living between the Altai and Lake Baikal along the Sayan mountains, are genetically close to Amerindians.[citation needed] This view is shared by other researchers who argue that “the ancestors of the American Indians were the first to separate from the great Asian population in the Middle Paleolithic.”[196][197] 2012 research found evidence for a recent common ancestry between Native Americans and indigenous Altaians based on mitochondrial DNA and Y-Chromosome analysis.[198] The paternal lineages of Altaians mostly belong to the subclades of haplogroup P-M45 (xR1a 38-93%;[199][200][201] xQ1a 4-32%[199][200]).

These ancient Siberians also had some “European” DNA, as do modern Siberians, but they are most closely related to their neighbors to the south, throughout the rest of Asia. Native American DNA is super fascinating, but we don’t have time to get into it all. On the grand scale, Native Americans are genetically Asians, separated from the rest of the clade by (probably) a mere 13-20,000 years. (Somewhat coincidentally, the Dire wolf, Smilodon, giant beaver, ground sloth, giant Columbian mammoth (Mammuthus columbi), woolly mammoth, mastodons, giant short-faced bear, American cheetah, scimitar cats (Homotherium), American camels, American horses, and American lions all went extinct in North America around 12,000 years ago.)

On the grand scale of human history, (200,000 years, more or less,) 13-20,000 years is not very long, and the Native Americans have not diverged too much, physically, from their cousins in Asia. The G-allele mutation of the EDAR gene arose about 30,000 years ago somewhere in east Asia and gives both modern Asians and Native Americans (but not Europeans and Africans) their characteristic hair and skin tone. While Native Americans are clearly physically, culturally, and geographically distinct from other Asians, (just as Europeans and south-Asian Indians are distinct from each other,) they are genetically close enough that they unquestionably clade together in the greater racial schema.

As I’ve said before, my diagram is just one way to represent one aspect of the genetic (and physical) distances between people.

Here is another diagram, not mine, which tells the same story in a different way (though it estimates a much lower genetic distance between Bushmen and Bantus than I’d expect. Oh well. different studies get different results; that’s why replication and meta-analysis are super important):

The Melanesians of Papua New Guinea and Australia are in pink (there are some mixed Melanesian / Polynesian populations in the world, but our road trip skipped them.) Their nearest relatives are other south Asians and Polynesians, but those same south Asians are themselves more closely related to Europeans than Australians. Diagrammed like this, it’d be understandable to break off south Asians into one race and put Caucasians, Native Americans, and East Asians into a single race. And I suppose you could, if you wanted to and could get everyone else to start using your categories. Race is biologically real and quite obvious at the macro scale, but a few small groups like Aborigines and Bushmen introduce existential uncertainty that intellectuals can quibble over.I don’t think it would be terribly useful rearrangement, though, for all of the reasons discussed over the past three posts in this series.

Well, that’s the end of our big road trip! I hope you’ve enjoyed it, and that it’s cleared up that nagging question people seem to have: How can Nigerians be more closely related to Europeans than some other Africans? Have a great day, and enjoy the drive home.

Race: The Social Construction of a Biological Reality, pt 2

Note: This post still contains a lot of oversimplification for the sake of explaining a few things.

Welcome back to our discussion of the geographic dispersion of humanity. On Tuesday, we discussed how two great barriers–the Sahara desert and the Himalayas + central Asian desert–have impeded human travelers over the millennia, resulting in three large, fairly well-defined groups of humans, the major races: Sub-Saharan Africans (SSA), Caucasians, and east Asians.

Of course, any astute motorist, having come to a halt at the Asian end of our highway, might observe that there is, in fact, a great deal of land in the world that we have not yet explored. So we head to the local shop and pick up a better map:

race2

Our new map shows us navigational directions for getting to Melanesia and Australia–in ice age times, it instructs us, we can drive most of the way. If there isn’t an ice age, we’ll have to take a boat.

900px-oceania_un_geoscheme_-_map_of_melanesia-svgThe people of Melanesia and Australia are related, the descendants of one of the first groups of humans to split off from the greater tribe that left Africa some 70k ago.

As the name “Melanesian” implies, they are quite dark-skinned–a result of never having ventured far from the equatorial zone.

Today, they live in eastern Indonesia, Papua New Guinea, Australia, and a smattering of smaller islands. (Notably, the Maori of New Zealand are Polynesians like the Hawaiians, not Melanesians, descendants of a different migration wave that originated in Taiwan.)

There is some speculation that they might have once been wider-spread than they currently are, or that various south-Asian tribes might be related to them, (eg, “A 2009 genetic study in India found similarities among Indian archaic populations and Aboriginal people, indicating a Southern migration route, with expanding populations from Southeast Asia migrating to Indonesia and Australia,”) but I don’t think any mainland group would today be classed as majority Melanesian by DNA.

They may also be related to the scattered tribes of similarly dark-skinned, diminutive people known as the Negritos:

Males from the Aeta people (or Agta) people of The Philippines, are of great interest to genetic, anthropological and historical researchers, as at least 83% of them belong to haplogroup K2b, in the form of its rare primary clades K2b1* and P* (a.k.a. K2b2* or P-P295*).[7] Most Aeta males (60%) carry K-P397 (K2b1), which is otherwise uncommon in the Philippines and is strongly associated with the indigenous peoples of Melanesia and Micronesia. Basal P* is rare outside the Aeta and some other groups within Maritime South East Asia. …

Naural blond hair
Two Melanesian girls from Vanatu (blond hair is common in Melanesian children.)

A 2010 study by the Anthropological Survey of India and the Texas-based Southwest Foundation for Biomedical Research identified seven genomes from 26 isolated “relic tribes” from the Indian mainland, such as the Baiga, which share “two synonymous polymorphisms with the M42 haplogroup, which is specific to Australian Aborigines“. These were specific mtDNA mutations that are shared exclusively by Australian aborigines and these Indian tribes, and no other known human groupings.[12]

A study of blood groups and proteins in the 1950s suggested that the Andamanese were more closely related to Oceanic peoples than African Pygmies. Genetic studies on Philippine Negritos, based on polymorphic blood enzymes and antigens, showed they were similar to surrounding Asian populations.[13]

Negrito peoples may descend from Australoid Melanesian settlers of Southeast Asia. Despite being isolated, the different peoples do share genetic similarities with their neighboring populations.[13][14] They also show relevant phenotypic (anatomic) variations which require explanation.[14]

In contrast, a recent genetic study found that unlike other early groups in Malesia, Andamanese Negritos lack the Denisovan hominin admixture in their DNA. Denisovan ancestry is found among indigenous Melanesian and Australian populations between 4–6%.[15][16]

Australian Aboriginal man

However, the Negritos are a very small set of tribes, and I am not confident that they are even significantly related to each other, rather than just some short folks living on a few scattered islands. We must leave them for another day.

The vast majority of Aborigines and Melanesians live in Australia, Papua New Guinea, and nearby islands. They resemble Africans, because they split off from the rest of the out-of-Africa crew long before the traits we now associate with “whites” and “Asians” evolved, and have since stayed near the equator, but they are most closely related to–sharing DNA with–south Asians (and Indians.)

So we have, here, on the genetic level, a funny situation. Melanesians are–relatively speaking–a small group. According to Wikipedia, thee are about 12 million Melanesians and 606,000 Aborigines. By contrast, Tokyo prefecture has 13 million people and the total Tokyo metro area has nearly 38 million. Meanwhile, the Han Chinese–not a race but a single, fairly homogenous ethnic group–number around 1.3 billion.

Of all the world’s peoples, Melanesians/Aborigines are most closely related to other Asians–but this is a distant relationship, and those same Asians are more closely related to Caucasians than to Aborigines.

As I mentioned on Tuesday, the diagram, because it is 1-dimensional, can only show the distance between two groups at a time, not all groups. The genetic distance between Caucasians and Aborigines is about 60 or 50k, while the distance between Asians and Caucasians is around 40k, but the distance between Sub-Saharan Africans and ALL non-SSAs is about 70k, whether they’re in Australia, Patagonia, or France. Our map is not designed to show this distance, only the distances between individual pairs.

Some anthropologists refer to Bushmen as "gracile," which means they are a little shorter than average Europeans and not stockily built
Some anthropologists refer to Bushmen as “gracile,” which means they are a little shorter than average Europeans and not stockily built

Now if we hopped back in our car and zoomed back to the beginning of our trip, pausing to refuel in Lagos, we’d note another small group that has been added to the other end of the map: the Bushmen, aka the Khoi-San people. Wikipedia estimates 90,000 San and doesn’t give an estimate for the Khoi people, but their largest group, the Nama, has about 200,000 people. We’ll estimate the total, therefore, around 500,000 people, just to be safe.

The Bushmen are famous for being among the world’s last hunter-gatherers; their cousins the Khoi people are pastoralists. There were undoubtedly more of them in the past, before both Europeans and Bantus arrived in southern Africa. Some people think Bushmen look a little Asian, due to their lighter complexions than their more equatorial African cousins.

Genetically:

Various Y chromosome studies show that the San carry some of the most divergent (oldest) human Y-chromosome haplogroups. These haplogroups are specific sub-groups of haplogroups A and B, the two earliest branches on the human Y-chromosome tree.[48][49][50]

Mitochondrial DNA studies also provide evidence that the San carry high frequencies of the earliest haplogroup branches in the human mitochondrial DNA tree. This DNA is inherited only from one’s mother. The most divergent (oldest) mitochondrial haplogroup, L0d, has been identified at its highest frequencies in the southern African San groups.[48][51][52][53]

I loved that movie
The late Nǃxau ǂToma, (aka Gcao Tekene Coma,) Bushman star of “The Gods Must be Crazy,” roughly 1944-2003

In a study published in March 2011, Brenna Henn and colleagues found that the ǂKhomani San, as well as the Sandawe and Hadza peoples of Tanzania, were the most genetically diverse of any living humans studied. This high degree of genetic diversity hints at the origin of anatomically modern humans.[54][55]

Recent analysis suggests that the San may have been isolated from other original ancestral groups for as much as 100,000 years and later rejoined, re-integrating the human gene pool.[56]

A DNA study of fully sequenced genomes, published in September 2016, showed that the ancestors of today’s San hunter-gatherers began to diverge from other human populations in Africa about 200,000 years ago and were fully isolated by 100,000 years ago … [57]

So the total distance between Nigerians and Australian Aborogines is 70k years; the distance between Nigerians and Bushmen is at least 100k years.

When we zoom in on the big three–Sub-Saharan Africans, Caucasians, and Asians–they clade quite easily and obviously into three races. But when we add Aborigines and Bushmen, things complicate. Should we have a “race” smaller than the average American city? Or should we just lump them in with their nearest neighbors–Bushmen with Bantus and Aborigines with Asians?

I am fine with doing both, actually–but wait, I’m not done complicating matters! Tune in on Monday for more.

Race: The Social Construction of Biological Reality

Note: This post contains a lot of oversimplification for the sake of explaining a few things. (Yes, I am still meditating on the greater Asian clade.)

Imagine you’re driving down a long highway that stretches from Nigeria to Beijing, passing through Berlin and New Delhi. In reality this route takes some large twists and turns, but we’re drawing it as a straight line, for all maps must simplify to be useful.

As you drive along, you pass many houses along the way–sometimes just a few clustered next to the highway, sometimes small towns, sometimes megalopolises with billions of people.

race

Our drive begins in one such megalopolis, that of Sub-Saharan Africa (SSA.) Here we meet people like Queen Anna Nzinga, author Chinua Achebe, and–though they have traveled far abroad–African Americans like Oprah Winfrey and Martin Luther King.

Though thousands of different languages are spoken by the thousands of different groups throughout SSA, we may still note a certain physical similarity among them–dark skin perfectly adapted to the equator’s strong sun, dark eyes, and tightly curling hair. While there is a tremendous amount of variety here–probably the most of any megalopolis in the world–they are also, quite clearly, related. You don’t have to go measuring skulls to figure that out.

But as we drive north, the houses thin out. Suddenly we are in a zone with almost no people–an enormous desert: the Sahara.

We speed through this harsh, empty landscape on a starry night, spotting only a few camels in the distance. We’re lucky we have a full tank of gas and several more in the trunk–for all but the most intrepid of our pre-automobile ancestors, this desert was nigh impassible, a vast barrier to human movement.

Finally we reach the vast inland sea of the Mediterranean, and the beginning of our second megalopolis. Most of the people here, from Berbers to Egyptians, have their own distinct look, more similar to their neighbors from the Middle East and Southern Europe than their neighbors to the south, across the inhospitable expanse of sand.

While there are many different countries and languages, no clear phenotypic line separates the people of Northern Africa, the Middle East, southern Europe, or northern Europe. Skin pales, hair lightens and becomes wavy, eyes turn a variety of hues as one nationality melts into the next. North-central Europe is the only place in the world where blue/green/hazel eyes and blond hair are common in adults; even in Wales, dark hair is dominant.

We hang a right through Turkey, Iran, Pakistan, and India, teeming with people.  Here again, though the people change and there are barriers like the Thar Desert, we find no harsh, nigh-impenetarable breaks like the Sahara.

Then, suddenly, we run smack into a wall, a natural wall of majestic proportions: the Himalayas. Beyond lie the Tibetan Plateau, Gobi Desert, and the vast emptiness of the Asian steppe. If this land was ever densely populated, generations of marauding steppe warriors have wiped them out. We see a few people here–aptly named Tibetan lamas, flocks of sheep grazing beside a scattering of yurts. Mongolia holds the distinction of being the world’s least densely populated independent country. (Ice-covered Greenland is even less dense, but owned by Denmark.)

Finally we pass beyond the shadow of the Great Khan’s memorial and into the valley of the Yellow River, where we find our third megalopolis: east Asia.

There is notably less genetic diversity here than in the first megalopolis–indeed, 93% of Han Chinese share a particular variety of the EDAR allele:

A derived G-allele point mutation (SNP) with pleiotropic effects in EDAR, 370A or rs3827760, found in most modern East Asians and Native Americans but not common in African or European populations, is thought to be one of the key genes responsible for a number of differences between these populations, including the thicker hair, more numerous sweat glands, smaller breasts, and dentition characteristic of East Asians.[7] … The 370A mutation arose in humans approximately 30,000 years ago, and now is found in 93% of Han Chinese and in the majority of people in nearby Asian populations.

Here, too, skin tones vary from north to south, though not as greatly as they do closer to the Greenwich Meridian. Most people have dark eyes, slim frames, and straight, smooth black hair.

Here in the megalopolis made famous by Beijing, Shanghai, Hong Kong, Seoul, and Tokyo, we have come to the end of the–first round–of our journey. From Africa to Asia, we have found three vast areas filled with people, and two major barriers which–though not completely impassible–have hindered humanity’s footsteps over the millennia.

People sometimes try to claim that human races do not exist simply because edge cases exist, small, scattered groups which possess a mixture of genes common to both Sub-Saharan Africans and Caucasians, Caucasians and Asians. And these groups do in fact exist, and are fascinating in their own rights. But these groups are also small, often living in extremely harsh, forbidding lands where few humans can survive (The inhabitants of the Himalayas and Tibetan plateau, I note, actually carry a gene that helps them survive at high altitudes which they received via an ancestor’s dalliance with a Denisovan hominin–the Denisovans were cousin to the Neanderthals and lived in Asia long before Homo Sapiens. No one else in the world carries this gene, so if you don’t have it, good luck living up there!)

But the vast, vast majority of the world’s people do not live in these harsh and unforgiving lands. They live clustered together in the enormous population centers, continually mixing, migrating, churning, and conquering each other, not people thousands of miles off. The concept of race stems from this basic observation of the geography of human settlements.

Physical distance is genetic distance, but since my diagram is only two-dimensional, it can only show the genetic distance between two points at a time. The genetic distance between Asians and Caucasians is about 40k years–much shorter than the distance between Sub-Saharan Africans and Caucasians, 70k years. But the distance between Sub-Saharan Africans and Asians is also about 70k years. Although Asians and Caucasians split apart from each other about 40,000 years ago, they are both descended from a single group of ancestors (a handful of Denisovans and Neanderthals excluded) who left sub-Saharan Africa about 70k years ago. We may best think of the relationship between these three groups not as a single highway, but as a triangle with two sides 70k long and one side of 40k. But to accurately add more groups to our journey, (as we shall do on Thursday), we would have to keep adding dimensions, and we are aiming here for simplicity, not n-dimensional hypercubes.

Humanity's path out of Africa
Humanity’s path out of Africa

The history of humanity’s long sojourn across the globe has resulted in, more or less, three main super-clades, or races: Sub-Saharan Africans, Caucasians, and Asians. The words we use for these are not perfect (“Caucasian” is particularly imprecise,) but do the job well enough.

Genetic distance map of 18 human groups, by Saitou Naruya https://en.wikipedia.org/wiki/Mongoloid#/media/File:Neighbor-joining_Tree-2.png
Genetic distance map of 18 human groups, by Saitou Naruya

The Asian super-clade has three main branches: Melanesians (and Aborigines,) who traveled south into the Pacific; the Native Americans, who settled North and South America some 13-40,000 years ago; and of course the East Asians, like the Chinese, Japanese, and Polynesians.

(Amusingly, Indians, though they clearly live in Asia, are part of the Caucasian clade because they are more closely related to Middle Easterners and Europeans than Chinese people. As a result, Indians were–for a while—recorded as “white” on US censuses, though today they are recorded as “Asian.”)

People are fond of saying that the SS African race contains the greatest genetic diversity (as well it might, due to the inclusion of groups like the Pygmies and Bushmen, who may have split off from other human groups over 100,000 years ago,) but the Asian race has the greatest pre-Columbian geographic/environmental range, stretching from Australia and Polynesia to Siberia and Greenland, from Mongolia to Patagonia.

Locations of Asian, Australian, and Melanesian ethic groups (including Indian, Middle Eastern, and Chinese) from Haak et al’s dataset

Trying to offer a single, coherent description of the physical appearances of such a diverse range of peoples is nearly impossible. They range in skin tone from almost white to as black as most of Africa; in stature from slight, Pygmy-like Negritos to the formidable Comanches (who in the 1800s were among the world’s tallest measured people;) and in average reported IQs from >105 to >65. (Okay, IQ isn’t appearance.)

We will be able to speak much more meaningfully about appearances when we address each of the sub-races.

Here are the relevant portions from Haak et al’s lovely dataset:

nativeamerican eskimoonge eastasian

On the left, we have the Native American DNA, from the depths of the Amazonian rainforest to the tribes of upstate New York. The olive green section are the Inuit/Eskimo and related Russian groups. The Inuit (who appear to have wiped out the earlier Dorset people,) share a great deal of DNA with other Siberians, eg the Yakuts (a Turkic people) and the Nganasan, (who speak a highly divergent language of the Samoyedic branch of the Uralic family, which also includes the Finnish, Hungarian, and Sami languages–language is a very bad guide to genetics.)

The pale peach are the Onge, who live in India’s Andaman Islands; purple the people of Papua New Guinea and Australia.

The very yellow part is all of the groups normally thought of as “East Asian,” like Japanese, Chinese, and Thai. Yellow is most dominant in the aboriginal people of Taiwan (who were there before the Chinese started migrating there in the past few hundred years,) and are the ancestors of the (not pictured) Polynesian peoples of Hawaii, Easter Island, and New Zealand. (I think they picked up some Melanesian DNA on the way.)

And on the right we have the various peoples of Siberia and central Asia.

I think it an open question whether the Melanesians and Aborigines ought to be properly classed with the other Asians, or awarded their own clade.

I totally stole this from Razib Khan, didn't I?
I stole this from Razib Khan, didn’t I?

According to Masatoshi Nei, a biology professor at Pennsylvania State University,[131]  the ancestors of today’s Asians and Caucasians split into two separate groups around 41,000 years ago, (give or take 15,000 years,) and their ancestors split from the ancestors of modern Africans–the “Out of Africa Event”–around 114,000 years ago, (give or take 34,000 years.)

 

The Daily Mail reports:

BERLIN (AP) — The human populations now predominant in Eurasia and East Asia probably split between 36,200 and 45,000 years ago, according to a study released Thursday.

Researchers used new techniques to analyze genetic samples from the shin bone of a young man who died at least 36,200 years ago near Kostenki-Borshchevo in what is now western Russia. The study, published in the journal Science, concludes that Kostenki man shared genetic sequences with contemporary Europeans, but not East Asians.

A separate study published last month in the journal Nature determined that a 45,000-year old sample found in Siberia contained sequences ancestral to both modern East Asians and Europeans.

Meanwhile:

In a genetic study in 2011, researchers found evidence, in DNA samples taken from strands of Aboriginal people’s hair, that the ancestors of the Aboriginal population split off from the ancestors of the European and Asian populations between 65,000 and 75,000 years ago—roughly 24,000 years before the European and Asian populations split off from each other. These Aboriginal ancestors migrated into South Asia and then into Australia…

A different study found:

The first complete sequences of the Y chromosomes of Aboriginal Australian men have revealed a deep indigenous genetic history tracing all the way back to the initial settlement of the continent 50 thousand years ago, according to a study published in the journal Current Biology today.

The Native Americans much more conveniently split off around 25,000 years ago.

Or in other words:

So on the one hand, race is biological and real, and on the other, it’s a social construct. Australian Aborigines are more closely related to other Asians than to, say, Europeans or Africans, but the Chinese are more closely related to Europeans than to Aborigines.

nature-siberian-neanderthals-17.02.16-v2One reason why Australians and other Melanesians appear so divergent from other Asian populations maybe their Denisovan (or other human) DNA. Most (if not all) human groups appear to have picked up DNA from some other, non-Homo Sapiens source. Europeans, East Asians, and Native Americans all have a small percent of Neanderthal DNA. Africans, IIRC, have a small % of some local African homin. And Melanesians/Australians have a small % of Denisovan DNA (Denisovans were a less-well-known cousin of the Neanderthals.)

Creationism, Evolutionism, and Categories

I’ve been thinking about the progression of ideas about natural categories, such as “men” and “women,” “cows” and “mules,” “English” and “Polynesian.” Not exactly our high philosophical progression, but a somewhat commoner one.

It seems that 100 years or so ago, most people would have explained the differences between things with a simple, “Because God wanted them to be that way.” And if God wants it that way, then the way they are is good and you should leave them alone.

I have heard my [sibling] wax practically poetic about the way God made mules and horses for farm work, and why you should not yoke together an ox and a donkey. (One of the interesting parts of meeting my siblings for the first time as an adult was realizing that dorkiness is genetic.)

The evolutionary perspective is that evolution created things (or, as we like to call it around here, GNON, the God of Nature and Nature’s God.) Gnon and God are functionally rather similar, for Gnon also made things in natural categories, and while we may refrain from deeming them “good” in quite the same way as religious people, we certainly believe that each group’s features serve purposes that have helped members of that group survive where others did not.

The conservative creationist denies the role of evolution, but he does not deny that categories exist. He merely disputes their method of creation. To quote Answers in Genesis:

So, a good rule of thumb is that if two things can breed together, then they are of the same created kind. …

As an example, dogs can easily breed with one another, whether wolves, dingoes, coyotes, or domestic dogs. When dogs breed together, you get dogs; so there is a dog kind. It works the same with chickens. There are several breeds of chickens, but chickens breed with each other and you still get chickens. So, there is a chicken kind. The concept is fairly easy to understand.

But in today’s culture, where evolution and millions of years are taught as fact, many have been led to believe that animals and plants (that are classed as a specific “species”) have been like this for tens of thousands of years and perhaps millions of years. So, when they see things like lions or zebras, they think they have been like this for an extremely long time.

From a biblical perspective, though, land animals like wolves, zebras, sheep, lions, and so on have at least two ancestors that lived on Noah’s Ark, only about 4,300 years ago. These animals have undergone many changes since that time. But dogs are still part of the dog kind, cats are still part of the cat kind, and so on. God placed variety within the original kinds, and other variation has occurred since the Fall due to genetic alterations.

For all that people accuse the Answers in Genesis folks of being crazy, and for all that they are trying awfully hard to re-invent the wheel, this is an unobjectionable approach to species and hybridization.

By contrast, the liberal creationist, since she cannot fall back on God in his rejection of Gnon, asserts that the categories themselves do not exist. “Race is a social construct. Gender is a social construct.” etc. Dr. Zuleyka Zevallos, who is definitely not a crazy Creationist with no respect for science, writes:

When people talk about the differences between men and women they are often drawing on sex – on rigid ideas of biology – rather than gender, which is an understanding of how society shapes our understanding of those biological categories.

Gender is more fluid – it may or may not depend upon biological traits. [bold mine.] More specifically, it is a concept that describes how societies determine and manage sex categories; the cultural meanings attached to men and women’s roles; and how individuals understand their identities including, but not limited to, being a man, woman, transgender, intersex, gender queer and other gender positions. …

The sociology of gender examines how society influences our understandings and perception  of differences between masculinity (what society deems appropriate behaviour for a “man”) and femininity (what society deems appropriate behaviour for a “woman”). We examine how this, in turn, influences identity and social practices. We pay special focus on the power relationships that follow from the established gender order in a given society, as well as how this changes over time.

And the New York Times writes:

Race is not biological. It is a social construct. There is no gene or cluster of genes common to all blacks or all whites. Were race “real” in the genetic sense, racial classifications for individuals would remain constant across boundaries. Yet, a person who could be categorized as black in the United States might be considered white in Brazil or colored in South Africa.

Answers in Genesis understands genetics better than the New York times or people with doctorates from actual universities. That is pretty damn pathetic.

Of course, some of our ideas about what “men” and “women”  or “blacks” and “whites” are like are cultural (especially any that involve technology, since technology has changed radically over the past 100 years.) As an amateur anthropologist, I am quite aware that different cultures have different ideas on these subjects. This does not negate the fact that “maleness” and “femaleness” are basically biologically-driven. Female interest in babies and male interest in violence has its roots in biology, not culture. Genetics have a huge effect on personality. Likewise, races are absolutely real, biological categories, which no doctor attempting an organ transplant can afford to ignore.

The idea that races don’t exist in some kind of genetic way is absurd. Let’s just take the EDAR gene:

Ectodysplasin A receptor (EDAR) is a protein that in humans is encoded by the EDAR gene. EDAR is a cell surface receptor for ectodysplasin A which plays an important role in the development of ectodermal tissues such as the skin.[3][4][5] …

A derived G-allele point mutation (SNP) with pleiotropic effects in EDAR, 370A or rs3827760, found in most modern East Asians and Native Americans but not common in African or European populations, is thought to be one of the key genes responsible for a number of differences between these populations, including the thicker hair, more numerous sweat glands, smaller breasts, and dentition characteristic of East Asians.[7]… The 370A mutation arose in humans approximately 30,000 years ago, and now is found in 93% of Han Chinese and in the majority of people in nearby Asian populations. The derived G-allele is a mutation of the ancestral A-allele, the version found in most modern non-East Asian and non-Native American populations.

Most East Asians and Native Americans (that is, the greater Asian Race,) have the G-allele of EDAR. Most non-Asians have the A-allele.

If you don’t have some form of causality to explain how the world’s variation came to exist, I guess you fall back on “it’s totally random and meaningless.”

Wise Tim, Crime, and HBD: part 5/5

Okay, so we are finally coming to the end of this series. Today we are going to discuss Flaherty and Sethi’s Homicide in Black and White (pdf):

African-Americans are six times as likely as white Americans to die at the hands of a murderer, and roughly seven times as likely to murder someone. Young black men are fifteen times as likely to be murdered as young white men. This disparity is historic and pervasive, and cannot be accounted for by individual characteristics. … We argue that any satisfactory explanation must take into account the fact that murder can have a preemptive motive: people sometimes kill simply to avoid being killed. As a result, disputes can escalate dramatically in environments (endogenously) perceived to be dangerous, resulting in self-fulfilling expectations of violence for particular dyadic interactions, and significant racial disparities in rates of murder and victimization. … Differences in the manner in which the criminal justice system treats murders with victims from different groups, and differences across groups in involvement in street vice, may be sufficient to explain the size and pattern of the racial disparity.

World-Murder-Rate-Geocurrents-Map-1024x726Well, I must give this one credit for offering up a new hypothesis: black people murder each other so often because they believe that other black people are murderous and are trying to avoid being the victim by killing the other guy first.

This makes sense in a Hobbesian, Napoleon Chagnon studying Yanomamo tribesmen kind of way. (If only there existed some kind of state-run institution that had historically cut discouraged homicide by punishing murderers so that people could go about their business in the heart of American cities without fear of Amazonian jungle-style violence.)

cobiptaumaactcrThe fact that whites do not go out of their way to preemptively murder blacks to the same degree that blacks murder other blacks suggests that whites don’t think blacks are as violent as other blacks do. This is a curious implication, all things considered, but not unreasonable. Aggressively “paranoid” behavior/belief that one’s neighbors are likely to be violent toward you is probably heritable, itself a result of having ancestors whose paranoia about their neighbors enabled them to survive in a hostile, homicide-ridden environment.

Flaherty and Sethi continue:

The magnitude of the difference in murder and victimization rates far exceeds any difference in characteristics that appear to predispose people to kill and be killed: being poor, being a highschool dropout, living in a dense urban environment, or being raised in a single-parent household, for instance. Blacks are about 2.75 times as likely as whites to be poor, 2.2 times as likely to be high-school dropouts, 2.9 times as likely to live in a large city, and 2.7 times as likely to grow up in a single parent household–all ratios that are far below the observed ratios for murder victimization and offending.

Well, that’s interesting.

Moreover, the racial homicide gap is long-lasting and widespread, and is much greater in cities and among young men than in other places or among other age-gender groups. In rural areas, there is no racial disparity in murder. The homicide gap is also much larger than the racial disparity in aggravated assault–in some ways the crime closest to murder–and there is no racial disparity in aggravated assault among young men.

Oh?

Okay, so, our authors are clearly lying: blacks commit aggravated assault at 7x the rate of whites, which is not that different from their rate of 8.5x murder rate. (And, in general, the Color of Crime report demonstrates that incarceration rates reflect actual offending rates.)

crdgu1gwgaaycfbUnfortunately, the authors don’t cite any evidence to back up their claim that in rural areas, blacks and whites have equal homicide rates, but as mentioned before, this seems a little problematic, given that the entire continent of Africa has fairly low population density and still has fairly high homicide rates. And why would rural environments make white people more likely to murder each other and black people less likely? Why would cities cool whites’ murderous tempers while inflaming blacks’? Why aren’t any of the world’s most violent cities located in India or China?

Even if we are just looking at selection effects–murderous whites like living in the countryside; murderous blacks like living in cities–we still have to wonder Why?

The Wikipedia page on Statistical Correlations of Criminal Behavior doesn’t mention neighborhood density.

The Atlantic notes:

There’s a big increase in crime as density rises from rural to urban, because crime thrives on anonymity–you don’t rob your neighbors, not necessarily because you like them, but because the likelihood of being identified is very high.  In an urban environment, random assaults like Matt’s are much easier to get away with.

While researching this post, I came across some very interesting thoughts on Density and Human Behavior:

Researchers in the social sciences have long tried to explain the effects of urbanization on the human animal. Of special interest has been the observed rates of crime and deviant behavior found in cities. In the United States city crime rates are higher than suburban rates, which in turn are higher than rural rates. …

Two major theories have developed to explain the effects of density on human behavior. Wirth’s (1938) is the most common with his famous statement that size, density and heterogenity explain the effects of urban life on the human animal.  The experiments done by Milgram (1970) suggest that when people are confronted with a large number of strangers in everyday life, they tend to withdraw and take less interest in the community in order to protect themselves from overload. Wolfgang (1970), among others, suggests that urban withdrawal and anomie resulting from density explains higher urban crime rates.

Animal studies made famous by Calhoun (1962) show that crowding in the animal world results in what he calls the behavioral sink. Normal behavior and reproductive habits fail. Aggressive behavior increases when density passes a certain point as animals compete for resources. In the experience of the reviewer, those who deny any possible connection between any human behavior simply say that humans are not animals so there can be nothing learned from animal experiments. However, human animals do seem to exhibit much lower fertility rates in cities than is true in rural areas. …

Using data from the Toronto Mental Health and Stress study (Turner and Wheaton 1992), Regoeczi looks at crowding in housing using the measure of persons per room. …

There is an optimal relationship between crowding and withdrawal.  The optimal point is 1.18 persons per room. This relationship holds even when the control variables are introduced. “The threshold for aggression is identical to that for withdrawal: 1.18 persons per room. After this point, the deleterious effect of density begins to take off and increased crowding leads to more aggressive responses among individuals.”

Cabrini Green, circa 1960
Cabrini Green, circa 1960

In other words, it’s probably safe to conclude that Cabrini Green and Pruitt Igoe, despite the good intentions behind them, were inhuman hellscapes that would drive any sane person to despair.

On the other hand, Manila, Philippines, is (according to Wikipedia) the densest city in the world, at 41,500 people per square kilometer, (or 107,500 people per square mile,) and it isn’t even ranked in the top 50 most murderous cities.

So while density may cause anomie, despair, plunging birth rates, and even anime consumption, it is clearly not the only ingredient involved in making some people murder their neighbors at higher rates than other people.

The best explanation I’ve come across for why our authors might have found closer to equal crime (not murder, haven’t found that) rates in rural areas than in urban areas comes, again, from La Griffe du Lion’s Politics, Imprisonment, and Race:

We all know that African Americans are imprisoned disproportionately to their numbers in the general population. According to the last decennial census a black man was 7.4 times more likely than his white counterpart to be incarcerated. In the language I’ll use today, we would say that the disparity or incarceration ratio was 7.4. State-by-state, the figures varied widely from 3.1 to 29.3. But contrary to expectation, the highest disparity ratios turned up mostly in politically progressive states, while the smallest ratios were mostly found in conservative states. Though the numbers change a bit from year to year, this racial-political pattern of imprisonment endures. One of the questions I will answer today is, why?

La Griffe’s answer is that more conservative (read, rural) states criminalize more behavior and so put more people in prison. Liberal states are more likely to put only the worst criminals behind bars, resulting in even more disproportionate imprisonment of blacks.

But returning to our PDF:

We begin with a baseline model in which race is the only visible characteristic, and the distribution of unobserved characteristics may differ across groups. In this setting, we explore two possible mechanisms through which significant racial disparities in homicide rates can arise. First, suppose that the costs of committing murder are contingent on the identity of the victim, with murders less likely to be solved and less aggressively prosecuted if the victims are black. … But this means
that blacks face greater danger in all their interactions, and are more likely therefore to kill preemptively. Anticipating this, whites will be more likely to kill preemptively in interactions with blacks than in interactions with other whites.

ct4h54nviaa6mabWhile it appears to be true that people who murder blacks (primarily other blacks) receive lesser sentences than people who commit similar crimes against whites*,** (which makes the disparities between black and white prison populations all the more concerning,) I don’t think this gets us to “blacks are vastly more likely to murder each other than whites are to murder blacks.” If it’s perceived as “open season” on killing blacks, then blacks and whites will kill blacks. And if blacks are killing back in self-defense (or perceived self-defense,) then they’re going to kill other blacks and whites.

*Note that there is an even greater disparity in sentencing between people who kill men and people who kill women, but no one suggests that this disparity is driving male-on-male violence.

**Note also that this does not imply that “society thinks black lives matter less than white lives,” as these lesser sentences maybe a result of black juries being more sympathetic toward black criminals than white juries toward white criminals.

Back to the PDF:

The second mechanism is based on costs of murder being contingent on the identity of the offender rather than the victim. Systematically lower incomes and higher rates of unemployment among blacks make the penalties for attempted murder or manslaughter lower for blacks relative to their outside options.

source

This is an interesting theory, but it’s kind of destroyed by the fact that high-income blacks still have higher homicide rates than lower-income whites.

So, even before we get to the paper’s math (and Flaherty and Sethi certainly do a lot of math,) I have a lot of disagreements with the paper’s basic assumptions. I don’t dispute the authors’ basic Hobbesian sense that your chances of being punished for a crime or your fear of being murdered by someone else can influence behavior, and I agree that black communities would probably be better served by locking away more criminals so that innocent black people can live in peace instead of fear, but I also think they are ignoring some pretty big behavioral correlations (ie, the behavior of people in Africa; the behavior of people in other dense places,) and have failed to ask themselves why they think people got the notion that crime rates are high in black communities in the first place.

In other words, they’re not entirely wrong, but they’re missing some big pieces of the puzzle.
